Important
update_the_devilboxIssues are constantly being fixed. Before attempting to spend too much time digging into your issue, make sure you are running the latest git changes and have pulled the latest Docker images.
Also keep in mind that configuration files might change, so ensure to diff the default ones against your currently active ones for added, removed or changed values.

Sudden unexplained problems on Windows
In case something stopped working for no reason, check out other Docker container. If you experience similar issues as well, check for any unattended Windows updates or updates to Docker itself. If those exist, try to revert them and see if that was the cause.
I heard many bug stories from fellow Windows users so far. A good contact point for that is the Docker forum itself: https://forums.docker.com/c/docker-for-windows
Address already in use
One of the Docker container wants to bind to a port on the host system which is already taken. Figure out what service is listening on your host system and shut it down or change the port of the affected service in the Devilbox .env file.
Some examples of common error messages:
Error starting userland proxy: Bind for 0.0.0.0:80: unexpected error (Failure EADDRINUSE)Unable to finish Pulling as unauthorized: incorrect username or password
This error might occur if you are already logged into a different Docker repository. To fix this error, sign out of your currently logged in repository and try again.
localhost or 127.0.0.1 not found
If you are using Docker Toolbox, the Devilbox intranet is not available on localhost or 127.0.0.1, but rather on the IP address of the Docker Toolbox machine.

ERROR: Version in "./docker-compose.yml" is unsupported
This simply means your Docker and/or Docker Compose versions are outdated.

Web server issues
403 forbidden
This error might occur for the Devilbox intranet or custom created projects.
File and directory permissions
On of the cause could be wrongly set file and directory permissions.
First ensure the cloned git directory is readable for users, groups and others.
For the Devilbox intranet, ensure the .devilbox/ directory is readable for users, groups and others. Also check files and directories within.
For projects, ensure an index.php or index.html exists and that all files and directories are readable for users, groups and others.
Shared volumes
This might additionally occur on MacOS or Windows due to the Devilbox and/or its projects not being in the standard location of Docker Shared volumes.
Check your Docker settings to allow shared volumes for the path of the Devilbox and its projects.
504 Gateway timeout
This error occurs when the upstream PHP-FPM server takes longer to execute a script, than the timeout value set in the web server for PHP-FPM to answer.
For that to fix one must increase the PHP-FPM/Proxy timeout settings on the virtual host.
Database issues
Invalid bind mount spec
This error might occure after changing the path of MySQL, PgSQL, Mongo or any other data directory.
When you change any paths inside .env that affect Docker mountpoints, the container need to be removed and re-created during the next startup. Removing the container is sufficient as they will always be created during run if they don't exist.
In order to remove the container do the following:
host> cd path/to/devilbox
host> docker-compose stop
# Remove the stopped container (IMPORTANT!)
# After the removal it will be re-created during next run
host> docker-compose rm -fremove_stopped_container
[Warning] World-writable config file '/etc/mysql/docker-default.d/my.cnf' is ignored
This warning might occur when using howto_docker_toolbox_and_the_devilbox on Windows and trying to apply custom MySQL configuration files. This will also result in the configuration file not being source by the MySQL server.
To fix this issue, you will have to change the file permission of your custom configuration files to read-only by applying the following chmod command.
# Nagivate to devilbox git directory
host> cd path/to/devilbox
# Navigate to the MySQL config directory (e.g.: MySQL 5.5)
host> cd cfg/mysql-5.5
# Make cnf files read only
host> chmod 0444 *.cnf
